摘要：Piezoelectric inkjet printing technology has been widely used in recent years. A new method for driving waveform design was presented to overcome the limitations in traditional waveform design methods. In this paper, the Doppler vibration test was used to determine the time of voltage rising and falling section. According to the superposition principle of velocity wave, the time of voltage dwelling section was determined by the numerical simulation. The optimal parameters with t(rise) = 5 mu s, t(dwell) = 16 mu s and t(fall) = 3 mu s of unipolar trapezoidal driving waveform was obtained. By using this method, the number of experiments can be significantly reduced in the initial stage of the printhead development process. The experimental results proved the feasibility of this method.
